[somenameforme]

Imagine, for a minute, that it was a crime for a politician to try to pass unlawful laws. That would, sooner or later, be abused by the group with political control to effectively criminalize opposition. Declare their opponents' efforts unlawful, convict them, and they're out of the way.

You have to consider not only the effects of nominal usage, but also the effects of abuse. In this case, they're extreme.
